It all depends on what you want from your truck. I like the old school motors and BBC just look awesome. Since my 72 was a factory big block I kept it that way and wanted it to look as factory as possible. As for power, if its done right you can have fun and enjoy it. Mine has a built 511 CID with Eagle crank and H-Beam rods, Edelbrock Perf RPM heads, Edelbrock Perf RPM Airgap intake, CC Roller Tip rockers and Crane Roller cam. It also has a built T400 trans, 2200rpm stall and a Gear Vendors OD. Factory Dana 60 with a Yukon Locker and 4.10 gears. Its not monster numbers but it does have right at 600hp at 5200rpm and 700 tq at 4200rpm. I also run AC here in Texas when its hot and the motor never gets over 180. Just got to make sure you do the cooling right. I like the LS plat form and they do make power. But in my opinion they just dont look as good as an old school BBC.
